Neutron star cooling in transiently accreting low mass binaries: a new tool for probing nuclear matter by Possenti, A, Colpi, M, Page, D, Geppert, U

“…We find that the soft component of the quiescent luminosity of Aql X-1, 4U 1608-522 and of SAX J1808.4-3658 can be understood as thermal emission from a cooling neutron star with negligible neutrino emission. …”
